| Abstract: | A series of experimental pressure measurements inside internal flow fields employing the intensity-based method of pressure sensitive paint technique were depicted based on self-established optical pressure measurement system and indigenously developed pressure sensitive paint.These experimental measurements include the applications inside both the transonic cascade wind tunnel and the nationally unique axial dual counter-rotate compressor facility (ADCCF) of Northwest Polytechnical University (NPU).The test articles involved a single vane of a large bending angle in transonic cascade wind tunnel and the oriented vane inside ADCCF,and both the surfaces of interest were correlated with the suctions.The traditional pressure measurement using electronic pressure scanning has been simultaneously conducted in the cascade wind tunnel for comparison.The contrast of both results from optical pressure measurement and electronic pressure scanning has revealed that the feasible application of optical pressure measurement system in internal flow fields and in practical industrial engineering. |
